Fixture Apparatus and methods of manufacturing fixture apparatus. Fixture apparatus comprising: a first body to at least partially support an object, the first body including a structure having variable stiffness along at least a first axis of the first body.

A clamp has: a clamping set and a positioning set. The clamping set has a shaft pivotally connected to a first arm and a second arm, and the shaft is provided with an elastic member. The first arm and the second arm are kept open by the elastic member, and the first and second arms are extended downward with a first handle and a second handle. The first handle is provided with a first pin, and the second handle is provided with a second pin. The positioning set is pivoted on a middle section of the first and second handles with the first and second pins. The positioning set is approximately horizontal, and travel distance of the shaft is greatly reduced, which not only reduces the structural cost, but also effectively improves the smoothness of the shaft movement.

A clamping apparatus includes a shaft; a base body that is adjustable to different positions, e.g., heights, along the shaft; a clamping leg arranged to pivot into a first clamping position and a second clamping position; an arm that includes, and extends between, a first end portion connected to the base body and a second end portion connected to the clamping leg; and a handle configured to be moved (a) into a first position that locks the position of the base body relative to the shaft and provides a clamping force to the clamping leg, and (b) into a second position in which the base body is free to be shifted into different positions along the shaft, where moving the handle into the second position releases the clamping force.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

A cutting system is disclosed. The cutting system comprises a moving mechanism, a cutter mounted on the moving mechanism, a support table having a material plate disposed thereon, and a fixation device including a pressing plate having a row of teeth defining a row of teeth slots. The row of teeth press the material plate on the support table while the moving mechanism drives the cutter to move along edges of the row of teeth slots. The cutter cuts a plurality of workpieces out of the material plate by a single cutting process.

This apparatus supports gripping, manipulation and/or insertion or removal of a planar workpiece from a receptacle into which it fits tightly. The apparatus has two substantially identical rigid arms attached to one another at a single pivot point near their longitudinal center. One end of each arm forms a handle; pressing or releasing these two handles actuates the gripper. The other end of each arm has attached on its inside surface a rigid plate. Together these two substantially parallel plates form jaws to grip the planar workpiece. A spring attached to the two handles biases the jaws toward the closed position. An optional adjustable stop mechanism supports setting the gap between jaws when the apparatus is in the closed position. An alternative embodiment utilizes step-shaped jaws for applications where flat jaws are difficult to utilize.

A clamping device includes: a clamp assembly and an adjustment assembly, the clamp assembly comprises two symmetrical clamp arms which are oppositely hinged to each other. Each of the clamp arms includes two identical and parallel clamp pieces, and a jaw, the jaw is detachably connected between the two clamp pieces, a lower edge of the jaw includes, in order from left to right, a first arc-shaped section, a second arc-shaped section and a horizontal section, the bottoms of the first arc-shaped section, the second arc-shaped section and the horizontal section are at a same plane, the first and second arc-shaped sections are symmetrical to each other, an angle is defined between the first and second arc-shaped sections, a V-shaped groove is defined between the second arc-shaped section and the horizontal section, and the first and second arc-shaped sections are each longer than the horizontal section.

Embodiments disclosed herein generally relate to a pivotable clamp or vise. For example, the vise may clamp or secure a workpiece at a suitable position and/or orientation.

A clamping tool of the type including a C-shaped body and a drive screw with a threaded portion in mechanical communication with a threaded receiver in one end of the C-shaped body and including at least two threaded receivers in one end of the C-shaped body, each adapted to separately and independently receive and support the threaded portion of the drive screw. A backstop may be included with a backstop pin extending from a surface of the backstop and at least two non-collinear backstop bushings in a second end of the C-shaped body. The at least two non-collinear backstop bushings may each be adapted to receive and support the backstop pin of the backstop, thereby providing more than one position of the backstop on the C-shaped body.

A dual-interface coupler includes a utilities unit, a number of utility cables configured to provide a number of utilities to the utilities unit, a first coupling unit associated with the utilities unit, and a second coupling unit associated with the utilities unit. The first coupling unit is configured to mechanically couple the utilities unit to a first corresponding coupling unit and comprises a utility interface. The number of utilities are configured to flow from the utilities unit through the utilities interface. The second coupling unit is configured to mechanically couple the second coupling unit to a second corresponding coupling unit.
